Cattle Vaccination Schedule Australia: The Complete Guide

Vaccination is one of the highest-return investments in cattle management. A well-timed program protects your herd from clostridial diseases, reproductive losses, and respiratory illness — yet many producers are still running ad-hoc schedules based on what the local vet recommended years ago.

This guide pulls together a practical vaccination schedule suited to Australian conditions — whether you're running beef breeders in Queensland, dairy cows in Victoria, or backgrounding steers in New South Wales.

Core Vaccines for Australian Cattle

Most Australian cattle programs are built around two foundations: clostridial protection and reproductive disease management. Here's what the major vaccines cover:

5-in-1 (Pentavac, Ultravac 5in1)

The most common cattle vaccine in Australia. Protects against five clostridial diseases:

• Pulpy kidney (Enterotoxaemia) — especially dangerous in young, rapidly growing calves
• Black disease (Infectious necrotic hepatitis)
• Blackleg (Clostridium chauvoei)
• Malignant oedema (Clostridium septicum)
• Tetanus — important for any cattle undergoing procedures

7-in-1 (Ultravac 7in1)

Adds protection against two leptospirosis serovars (Hardjo and Pomona) to the clostridial five. Leptospirosis is a significant zoonosis — it can infect humans handling infected animals or urine. Highly recommended in areas with wet seasons, irrigation country, or wildlife pressure.

Botulism (Ultravac Botulism)

Critical in phosphorus-deficient country across northern and central Australia, where cattle chew bones (pica) and are exposed to botulinum toxin. Also recommended where carcasses accumulate near water. A single dose gives long-lasting protection.

Vibriosis (Bovine Venereal Campylobacteriosis)

Caused by Campylobacter fetus, this sexually transmitted disease causes early embryonic loss and repeat breeding. Vaccinate bulls and cows in natural mating programs — particularly important when introducing new bulls.

Pestivirus (BVDV)

Bovine viral diarrhoea virus causes immunosuppression, reproductive loss, and the birth of persistently infected (PI) calves who shed virus continuously. Vaccination is recommended in mixed herds or where biosecurity cannot be guaranteed. Testing and culling PI animals is the most effective long-term control.

Pinkeye (Infectious Bovine Keratoconjunctivitis)

Caused primarily by Moraxella bovis. Autogenous vaccines (made from your own herd's strains) tend to be more effective than commercial products. Worth pursuing if pinkeye is a recurring problem in summer.

Recommended Vaccination Schedule by Class

Class	Vaccine	Timing	Notes
Calves (first vaccination)	5-in-1 or 7-in-1	4–6 weeks of age	Colostrum immunity wanes by ~6 weeks
Calves (booster)	5-in-1 or 7-in-1	4 weeks after first dose	Two doses required for lasting immunity
Weaners	5-in-1 or 7-in-1	At weaning (if not already done)	High-risk period — stress + new pastures
Breeding cows (annual)	5-in-1 or 7-in-1	4–6 weeks pre-calving	Boosts colostrum antibodies for calves
Breeding cows	Vibriosis	4–6 weeks pre-joining	Annual booster; 2 doses first year
Bulls	Vibriosis	4–6 weeks pre-joining	Annual booster; 2 doses first year
Purchased cattle	5-in-1 or 7-in-1	On arrival	Assume no history; 2-dose primary course if unknown
High-risk/botulism country	Botulism	Once, then 3-yearly	Check label — some products require annual booster
Feedlot entry	7-in-1 + IBR + BVD	On induction	IBR and respiratory cover critical in feedlot settings

The Two-Dose Rule

Any animal receiving a vaccine for the first time needs two doses, 4–6 weeks apart, to develop lasting immunity. A single dose in a naïve animal provides only partial, short-lived protection. This is the most common mistake in cattle vaccination programs — producers give one shot and assume the animal is covered.

Once an animal has received a full two-dose primary course, annual boosters are generally sufficient to maintain immunity for most core vaccines.

Pre-Joining and Pre-Calving Windows

The two most important timing windows in a cow-calf program are:

Pre-joining (4–6 weeks before bulls go out)

This is when you want Vibriosis vaccination fully active for both bulls and cows. It's also a good time to administer annual boosters for the whole herd and complete any pregnancy testing or condition scoring that will affect joining decisions.

Pre-calving (4–6 weeks before first expected calving)

Vaccinating cows at this time maximises the concentration of antibodies in colostrum. Calves that receive good colostrum in the first 12 hours of life have significantly better immunity against pulpy kidney and other clostridial diseases in the first weeks of life.

Cold Chain and Vaccine Handling

Even a perfect schedule delivers poor results if vaccines are mishandled. Cattle vaccines are biological products that are destroyed by heat or freezing:

• Store between 2°C and 8°C — never freeze (except where the label specifically states)
• Use an insulated cooler with ice packs in the paddock — never leave vaccines in direct sunlight or a hot ute cab
• Discard any product that has been frozen, overheated, or left open for more than a day
• Check expiry dates before purchase — don't stock-up speculatively
• Use a new needle for every animal when vaccinating for reproductive diseases (especially Vibriosis)

Recording Your Vaccination Program

Good records are the foundation of an effective vaccination program. Without them, you can't confirm which animals have received a primary course, identify cattle due for annual boosters, or demonstrate your vaccination history to a buyer or insurance assessor.

At minimum, record for each vaccination event:

• Date administered
• Vaccine name and batch number
• Animals treated (tag numbers or mob)
• Who administered it
• Next due date

Paper records work, but they get wet, fade, and are hard to search when you need to know whether a particular cow received her Vibriosis booster before joining. A digital health record system makes this instant — and keeps your whole program visible in one place.

PaddockMate IQ lets you log health records and set recurring reminders against individual animals or whole mobs. When a vaccination is due, you get a notification — no more relying on memory or a calendar on the shed wall.

Working With Your Vet

The schedule above is a solid starting point, but the best cattle vaccination program is one designed specifically for your property, region, and production system in partnership with a local vet who knows your country.

A vet who conducts a property health plan visit can assess your:

• Disease history and herd exposure risk
• Regional disease prevalence (e.g., Botulism in phosphorus-deficient areas)
• Production system gaps (feedlot vs. pastoral vs. dairy)
• Reproductive performance data — often the first indicator that a vaccination program isn't working

Most state government agriculture departments also publish region-specific vaccination recommendations — worth checking for your area.
